EDOF stands for extended depth of field. Instead of fixed focal points (as with multifocal/trifocal), the optics create a continuous range of focus from distance to the intermediate distance (≈ 60–90 cm).
Advantage: very natural visual impression, calm night vision (potentially fewer halos) and stable PC range – ideal for everyday life, work and driving.
Memory aid (1 image, 1 metaphor): Like a modern autofocus that doesn’t just keep one point in focus, but a range.
EDOF lenses are particularly suitable if you …
At Eyelaser Wien, we check your anatomy, visual habits and goals in the preliminary examination – and individually select EDOF vs. (toric) alternatives.
| Criterion | EDOF | Trifocal | Monofocal (statutory health insurance) |
| Near | good–very good (everyday life, menu, labels); reading glasses may be necessary for very small print | very strong (often complete near vision freedom) | reading glasses required |
| Intermediate (PC, 60–80 cm) | very strong | very strong | medium |
| Distance | very good | very good | very good |
| Halos/glare | tendentially fewer | initially possible, usually decreasing | minimal |
| Visual impression | very natural, wide depth of field | 3 defined distances | clear at one distance |
| Freedom from glasses | high in everyday life; near-small print may require glasses | very high in all distances | low |
| Property | EDOF (e.g. Vivity, Eyhance) | Standard monofocal |
| Distance vision | excellent, brilliant | good |
| Intermediate (PC) | excellent, seamless | ❌ Workplace glasses required |
| Near (reading) | functionally good; small print may require reading aid | ❌ always reading glasses |
| Night vision/contrast | very good, low halo | very good, no halos |
| Visual impression | natural, fluid | only one sharp area |
| Freedom from glasses | high everyday independence | only for distance |
Anamnesis, vision profile (PC, night driving, sports), wishes
Exact measurement → decision EDOF vs. alternatives (possibly toric/“blended vision”)
Under drop anesthesia, micro-invasive, structured procedure
Check-ups in Vienna; quick return to everyday life/work, touch-up option for small residual values (depending on cornea/overall findings)
“EDOF bridges the gap between monofocal and trifocal. Those who prioritize visual quality and night comfort and want to be glasses-free in everyday life – especially at the PC – often make the best choice with EDOF.”
“Relaxed at the screen, clear in the distance – exactly what I was looking for.”
“Pleasantly calm at night, sharp everywhere during the day. I have fine reading glasses for small print – doesn’t bother me.”
Say goodbye to your reading glasses. The first step is a simple, non-binding suitability analysis in our clinic in Zurich.
Find out whether you can see sharply again with your own eyes.
Yes, I would like a free suitability analysis!Often yes, if presbyopia is present and you prioritize intermediate distances (PC, cooking, conversation). We check the cornea, macula, tear film, pupillary dynamics, and your visual goals. With astigmatism, toric EDOF variants are available. In individual cases (e.g., pronounced maculopathy), we recommend alternatives.
In everyday life usually yes (PC, car, shopping, TV). For small print at a short distance – especially in low light – a fine pair of reading glasses can occasionally be useful. We discuss this clearly in advance.
EDOF: wide range of focus, tendentially fewer halos, strong in the PC area, very natural impression.
Trifocal: maximum freedom from glasses in all distances including reading small print; initially halos possible, which usually decrease. Decision based on visual habits and priorities.
Many report the following day clear, calm vision. In the following weeks, the neuroadaptation gradually improves contrast and night vision.
The operation is performed on an outpatient basis and is painless under eye drop anesthesia. Short-term pressure/touch stimuli are possible. The procedure is standardized and will be explained in detail.
Yes, possible – tends to be rarer and less pronounced than with classic multifocal designs. We choose the lens design to match your profile and closely monitor the acclimatization.
That is a strength of EDOF: the intermediate range (≈ 60–80 cm) is stable and comfortable. Many find the laptop/PC vision to be very natural and relaxed.
Light activity usually after a few days. Swimming/sauna typically after about 2 weeks and medical clearance. Contact/ball sports individually.
The lens is designed for lifelong use designed. Since the natural lens is replaced, no cataracts can develop later.
Yes. We are planning a structured control plan (e.g. Day 1, Week X, Month X). If you have any questions, you have direct contact routes to the team in Vienna.
Depending on the cornea/overall findings, fine-tunings are possible (e.g. laser touch-up). We plan conservatively and prioritize safety and quality.
Yes. With astigmatism, toric EDOF implants are available. Selection based on biometry, axis, and stability.
We work with premium implants from leading manufacturers and select the design based on your visual profile (near, night comfort, screen work). We will discuss the details in the appointment.
With refractive motivation, usually no. With medical indication (e.g. cataracts), the respective insurance rules. We will support you in clarifying this.
Online or by phone. The initial consultation is non-binding and clarifies suitability, goals, and the best lens option (EDOF, trifocal, monofocal, toric). Appointments are usually available quickly.
